Resumen

HOJO, Ellen Toews Doll et al. Refrigerated storage of wax-coated grapefruit varieties Flame and Henderson. Ciênc. agrotec. [online]. 2010, vol.34, n.5, pp. 1261-1269. ISSN 1413-7054.  http://dx.doi.org/10.1590/S1413-70542010000500026.

The goal of this work was to study the conservation of grapefruit (Citrus paradisi Macfad.) "Flame" and "Henderson" coated with Sparcitrus wax and kept under refrigeration (8º C ± 1º C and 95% ± 5% RH). For each variety studied, the experimental design was completely randomized, build up in factorial 2 x 5, with 3 replicates, where the first factor corresponded to the treatments with and without wax application (control) and the second factor to the storage period (0, 10, 20, 30 and 40 days). Each experimental parcel was composed of five fruits. The following variables were studied: mass loss, yield of juice, pH, soluble solids (SS), titratable acidity (TA), SS/AT, reducing, non-reducing and total soluble sugars, ascorbic acid and external appearance. Wax application is effective in the preservation of the appearance of grapefruits "Flame" and "Henderson", and does not affect their internal quality.
